This page serves a US gasoline futures price in dollars per gallon, following the NYMEX RBOB contract. RBOB is a wholesale blendstock, priced before ethanol blending and before taxes, and it is roughly a dollar below the pump price for structural reasons this page quantifies. Three different numbers circulate as 'the gas price'; the sections below state which one this is.
What RBOB actually is
RBOB - Reformulated Blendstock for Oxygenate Blending - is the gasoline component refiners ship before roughly ten percent ethanol is blended in at distribution terminals. The NYMEX futures contract prices 42,000 gallons of it for physical delivery in New York Harbor, and CME's rulebook terminates trading on the last business day of the month before the delivery month. The price on this page is therefore a pre-ethanol, pre-tax wholesale price for the New York Harbor market, not a national retail average.
The gap to the pump price, quantified
The EIA decomposes the 2025 average retail price of $3.10 per gallon as 51.4% crude oil, 14.3% refining, 17.8% distribution and marketing, and 16.6% taxes - about fifty cents of tax alone. RBOB captures the first two components. The remaining third of the pump price is added downstream of this contract, which is why comparing this series to a pump price without adjustment overstates how cheap fuel is at the rack.
The seasonal specification step
US environmental rules cap gasoline volatility in summer, so summer-grade gasoline excludes cheap butane and costs more to make. The futures contract carries the summer specification for April through September delivery months, so the futures curve steps up at the March-to-April boundary and down at September-to-October - a specification change, not a market move. Our own series recorded the 2026 spring step precisely: the March contract stopped trading on Friday 2026-02-27 at $2.02, and the next capture - dated Saturday 2026-02-28 - printed the April summer-spec contract at $2.29, a +13.4% step from roll and specification combined, landing on a non-trading day because capture follows the sources' front-month switch. The exact contract month behind each observation is not asserted in our data. Not every large step is a roll: the 10.0% fall on Tuesday 2026-04-07 was an ordinary market move.
GASOLINE_USD is a different series, and was restated
We publish a second code, GASOLINE_USD, from a market-data blend. Until 2026-08-09 our documentation described that series as the EIA Gulf Coast conventional-regular spot assessment; measurement against our own EIA-sourced rows showed same-date differences reaching -9.3%, and the description was corrected: it is a blend that tracks wholesale gasoline, not the EIA assessment and not a retail price. On 2026-08-10 the two codes printed within a cent of each other - GASOLINE_USD at $3.10 and this RBOB series at $3.11. The restatement, its measured basis and the affected period are recorded in our public issue tracker.
Data freshness
Intraday observations from three sources - our internal collector (39.6%), a financial publisher (36.2%) and a data aggregator (24.2%) over the thirty days to 2026-08-10 - at a median gap of 2.6 minutes; on 2026-08-10 all three printed $3.11 within six minutes of each other. Our RBOB records begin 2025-02-15, so this is a young series; deep gasoline history on this site comes from the EIA-backed series instead.

Gasoline RBOB FAQ
Is this the price I pay at the pump?
No. This is a wholesale blendstock futures price before ethanol, taxes, distribution and retail margin. By the EIA's 2025 decomposition, those downstream components are about a third of the retail price.
What is the difference between GASOLINE_USD and GASOLINE_RBOB_USD?
GASOLINE_RBOB_USD follows the NYMEX RBOB futures contract. GASOLINE_USD is a market-data blend that tracks wholesale gasoline; its description was corrected on 2026-08-09 after measurement showed it is not the EIA Gulf Coast assessment it was once labeled as. The two currently print within a cent of each other.
Why does the futures price jump every spring and fall?
The contract specification changes: April through September delivery months carry the more expensive summer volatility spec, so the curve steps up going into April contracts and down going into October contracts, independent of market direction.
